Abstract
The oil reservoir is a system formed by liquid-tight cemented grains of rock and mobile fluid filling the space between them. The pore sizes in which fluid flow occurs, often very small, in the order of tens of micrometers. However, the physical processes that take place at these spatial scales, determine the properties of the whole range of filtration macro models. In this paper, by X-ray microtomography investigated the pore space of the core. Determine the values of porosity and permeability. Threedimensional model of the pore space is obtained. The process gas flow in the resulting pore space is studied by numerical simulation. It is shown that this approach can be used as the solution of various problems of flow visualization to identify the characteristics of the intensification of filtering imposed by elastic vibrations.
